The crawl utility starts a depth-first traversal of the web at the
|
|
specified URLs. It stores all JPEG images that match the configured
|
|
constraints. Crawl is fairly fast and allows for graceful termination.
|
|
After terminating crawl, it is possible to restart it at exactly
|
|
the same spot where it was terminated. Crawl keeps a persistent
|
|
database that allows multiple crawls without revisiting sites.
|
|
|
|
The main reason for writing crawl was the lack of simple open source
|
|
web crawlers. Crawl is only a few thousand lines of code and fairly
|
|
easy to debug and customize.
|
|
|
|
Some of the main features:
|
|
- Saves encountered JPEG images
|
|
- Image selection based on regular expressions and size contrainsts
|
|
- Resume previous crawl after graceful termination
|
|
- Persistent database of visited URLs
|
|
- Very small and efficient code
|
|
- Supports robots.txt
